I was updating a base server with the X540T2 card, and noticed that I lost remote access as the updates started to install. I went to teh physical server, and found that the NIC was no longer connected to the Internet. I allowed the updates to complete, and then on reboot, the NIC issue was still there.
The 2 ports of the X540-T2 (connected as just plain 10GBase-T to a X712 netgear hub), were listed as FCoE device in device manager - with a yellow caution triangle. I tried to reinstall the driver (downloaded the x64 .exe driver install from Intel website), and this still occurred.
I them manually selected the X540T2 driver from the list of available drivers, and the device came up, but there was still an error. I then used a driver from Sep2015 (manually selected), but when trying to set the IP address of the main port, I would get a preferred IP address (that I entered in teh static settings), and a tentative IP address (- that is not in my segment. The Tentative address would not go away.
I then ran out of time, and simply enabled the onboard 1Gbit ports, and configured those for Network, and HyperV, just so the server would not be down.
Any idea what is happening.
Other servers share the same hub with no problems (I did not try changing ports on the hub, but could do that - as I have a couple of free ports). Is there a clean way to completely uninstall all the drivers etc and reinstall?
